Octave stable (4.0.2) & dev now produce a scalar struct with empty fields which is not compatible with previous Octave and Matlab. As an example, this makes testing for a missing package go from: if(isempty(ver('mypackage'))) to: mypkg=ver('mypackage'); if(isempty(mypkg) || isempty(mypkg.Version)) I have attached a small patch to fix the issue (affects a single command within ver.m and adds a test). _______________________________________________________ File Attachments: ------------------------------------------------------- Date: Wed 15 Jun 2016 06:05:06 PM GMT Name: octave4_ver.diff Size: 1kB By: ggeuler <http://savannah.gnu.org/bugs/download.php?file_id=37492> _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/bugs/?48235> _______________________________________________ Message sent via/by Savannah http://savannah.gnu.org/
